Because it shows that often the highest jackpot games are also the worst to play.

By worst, I mean they have the highest odds.

Yet most of us (yes, including me) want to take part in these big-number-prize games. They have great kerb appeal, as real estate people would say.

In other words, a $500 million jackpot will get your eyes lighting up far more than a $5 million prize. That's quite normal for our primitive reptilian brains.

But here's the problem. Every number added on to a lottery game increases the odds dramatically.

NUMBERS COUNT

So if a game has 5 balls and the organisers decide to add a ball to make up 6, the odds take a huge whack.

When they increase the amount of numbers in the game, much the same problem happens.

However, this is done because it is often the only way they can offer huge prizes, and the result is that the street appeal is massive. More people buy, more money is funneled through to prizes, and the more the jackpot goes up. It's simple and effective marketing.

Take a look at the list of 5 'worst' games to play - the one that have the poorest playing odds:

If there is another game in your area with lower odds, play that instead.

When choosing what game to play, always go for the game with the lowest number of balls and numbers.

Play the high odds games only on special occasions, such as when the jackpot goes to $50-$100 million plus.

Reduce your expectations for winning the jackpot. The good thing about the high odds games is that they offer a large number of prizes in the other divisions. Even winning 2-5 third division prizes can add up to a nice surprise.

Whatever you decide, remember these tips that apply to all your lottery playing...

Make sure you continue to play regularly.

Spread the risk. For example, play 1 high-odds game to every 5 low-odds game, if you have a choice.
